Peer Effects & Differential Attrition: Evidence from Tennessee’s Project STAR

by Sanjay Satish

Abstract
This paper explores the effects of attrition on student development in early education. It aims to provide evidence that student departure in elementary schools has educational impacts on the students they leave behind. Utilizing data from Tennessee’s Project STAR experiment, this paper aims to expand upon the literature of peer effects, as well as attrition, in public elementary schools. It departs from previous papers by utilizing survival analysis to determine which characteristics of students prolonged participation in the experiment. Clustering analysis is subsequently employed to group departed students to better understand the various channels of attrition present in STAR. It finds that students who left Project STAR were more likely to be of lower income and lower ability than their peers. This paper then uses these findings to estimate the peer effects of attrition on students who remained in the experiment and undertakes a discussion of potential sources of bias in this estimation and their effects on the explanatory power of peer effects estimates.

Implications of Teacher Tenure on Teacher Quality and Student Performance in North Carolina

By Dana Fenster

This paper examines the relationship between teacher tenure and teacher quality in North Carolina, measured via student performance on the state End of Grade (EOG) standardized tests. After presenting a comprehensive synopsis of the current teacher tenure policy, I use data from the North Carolina Education Research Data Center (NCERDC) to compare demonstrated teacher effectiveness across the tenure bubble, defined as one to eight years of teaching experience within the same district. Ultimately, I find that there is significant jump in average teacher quality at the tenure cutoff, suggesting that tenure policy is effective in retaining high quality teachers while removing those who are ineffective.
